Patent CA-2248865-C (CA)
Inventor: HARRIS HOWARD
IPC: F24H1/20
Filed: 1998-10-02
Granted: 2003-03-18
Abstract: A pressureless electric water heater for domestic use has a cylindrical double-walled tank for holding a quantity of a heat transfer liquid such as water. Cold water enters a copper coil immersed in the heat transfer liquid. The heat transfer liquid is heated by an electric heating element which extends down from a hinged tank top and exits the coil as water heated by an electric heating element. The hinged top allows easy access to the interior of the tank and to the heating element, further easing access and replacement thereof. Sedimentation in the tank is minimized because the tank water is rarely replaced. Sedimentation is the coil reduced because pressurized water flows through the coil when hot water is required and continuously cleanses the pipe.

Abstract: A fluorescent ink that makes tagger marks and is able to be used in valve jet printers at a rate of four #10 envelopes per second. The ink also penetratespaper at a rapid rate and dries at the same time it is penetrating the paper, without degrading the print quality. The penetrating agent solvent system may be isopropyl alcohol in combination with a surfactant. The surfactant may be polyethylene glycol ethers. Polyethylene glycol ethers have a high boiling pointand low vapor pressure. The penetrating agent solvent system has a low boiling point and high vapor pressure and a low static and dynamic surface tension. This improves the inks rate of penetration into the paper and diminishes the amount of offset.

Title: Membrane virus host range mutations and their uses as vaccine substrates
Inventor: BROWN DENNIS T
IPC: C07K14/005
Filed: 1998-09-18
Granted: 2011-08-09
Abstract: The vaccines and methods of the present invention are based on deletion mutations in the protein transmembrane domains of membrane-enveloped viruses. The strategy for production of these mutations is based on the fact that unlike mammalian cell membranes, the membranes of insect cells contain no cholesterol; thus are thinner than mammalian membranes. Many membrane-coated viruses have membrane glycoproteins on their surface which are responsible for identifying and infecting target cells. These membrane glycoproteins have hydrophobic membrane-spanning domains which anchor the proteins in the membrane bilayer. The membrane-spanning domains of these transmembrane proteins must be long enough to reach from one side of the bilayer to the other in order to hold the proteins in the membrane. Provided is a vaccine, a method of producing this vaccine, and a method of using this vaccine, based on the differences between membranes of viruses replicated in invertebrates and membranes of viruses replicated in vertebrates.

Patent CA-2317670-C (CA)
Inventor: KURELEK JOHN
IPC: E02F9/22
Filed: 2000-09-06
Granted: 2002-07-16
Abstract: The two boom members and hydraulic cylinders of a knuckle boom tree harvesting machine are so arranged and proportioned that with a single control movement during reaching and retracting actions the working tool head is made to travel in an approximately horizontal path. The cylinders and control valve are so connected that during horizontal reaching action load-supporting pressurized oil from a collapsing cylinder is not required to be dumped to the reservoir in the conventional heat generating manner, but is rather shunted directly to an extending cylinder where it continues to do useful load support work. Energy waste to hydraulic oil heat and fuel consumption is significantly reduced. Although these advances have been particularly developed for disc saw felling and stroke delimbing of trees they can also be applied to other knuckle boom applications where horizontal reaching is a major function.
